Application fi1ed March 3, 1914. Serial No. 822,139.

To all whom it may concern Be it known that I, Lnwis P. CONKLIN, a citizen of the United States, and a resident of Red Bank, in the county of Monmouth and State of New Jersey, have invented certain new and useful Improvements in AntirattlingSash-Locks and Window-Stops, of which the following is a specification, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to certain new and useful improvements in locks'employed in connection with window sashes; and the main object of my invention is to provide a sash lock which can be made to do service as a window stop.

Another object is to provide a self-locking sash lock positive in operation and of a simple and durable construction.

A still further object is to provide a sash lock which will hold the sashes to the window frame to prevent rattling of the sashes.

With these and other objects in view, the present invention consists in the combination and arrangement of parts as will be hereinafter more fully described and finally pointed out in the appended claims, it being further understood that changes in the spe cific structure shown and described may be made within the scope of the claims without departing from the spirit of the invention.

In the accompanying drawings forming a part of this specification and in which like numerals of reference indicate similar parts in the several views: Figure 1 shows a fragmentary portion of a window frame and sashes equipped with a lock and stop embodying my invention, the lock being shown as serving as a stop. Fig. 2 shows a sectional detail disclosing the device as serving as a window lock. view of the lock. Fig. 4 is a section on line 1, 4, of Fig. 1. Fig. 5 shows an inner view of a window frame and sashes disclosing the upper sash as being lowered for ventilating purposes. Fig. 6 shows a modification of the lock. Fig. 7 shows the look as about to slide over one of the stops in the operation of closing the windows.

In my present invention, I provide a sash lock which is noticeable because of its extreme simplicity, and which is arranged to prevent the rattling of the sashes while the windows are open for ventilating purposes,

the construction further being such that the sashes cannot be moved beyond a predeter- Fig. 3 is a perspective mined distance either from within or without, without manually manipulating the lock, which however, automatically locks itself when the windows are closed.

In the drawings, the letter A, designates a, suitable window frame including the inner batten B, the outer batten B and the intermediate rail 0, between which the window sashes slide.

The numeral 10 designates the top stile and 11 the side stiles of the inner window frame, while the numeral 9 designates the bottom stile and S-the vertical stiles of the upper outer window sash.

In the use of my lock, the same is secured to the upper stile 10 of the inner window sash at a point opposite the vertical stile of the upper window frame in the manner shown in Fig. 1.

The lock comprises a fiat plate 12, preferably made of spring steel one end of which is bent cylindrically to form the pin sleeve 13. Within this sleeve is held a staple 17 the points 18of which are driven into the window stile to pivotally hold the sash lock in working position. The opposite end of the plate is continued in the form of a resilient ti-shaped beak head... One branch of each V is formed by a fiat section 1 1 which is bent obliquely outward while the other branch 15 is curved outwardly. The upper end of the curved branch is bent over to form the stop ledge 16 which ends in alinement with the body portion of the sash look, as shown in Figs. 1 and 3. r In securing the lock to the sash, the operator places the sash lock in an upwardly inclined position, so that the convex surface 15 of the v branch of the beak hGilCl'Wlll rest against a vertical stile 8. The staple 17 is then driven into the top stile 10. In this position of the lock, should the lower sash be raised, or the upper sash be lowered, the beak head will be impinged upon the stile 8, the branch 1e finally binding upon the'outer edge of the top stile 10, as shown in Fig. .1. In this position of the lock, the window sashes are firmly bound against the inner and outer battens and the window sashes can then only be advanced in exercising a force suflicient to overcome the frictional engagemay be in the form of ordinary wood screws positioned in the path of the beak head.

As shown in Fig. '1, the lower sash has been raised such a height that the beakhead has been brought into contact with the stop 5. V In this position of the lock, it is impossible to either raise the lower sash or lower the outer sash without first removing the stop pin 5, or lowering'the inner sash and manually carryingthe lock upward to permit the beak head escaping over the stop pin. In Fig. 1, the stop pin 5 is'located a 1 suitable distance above the lower stile 9 of the upper window'sash, so that the windows can be adjusted for ventilating purposes.

In Fig. 2, the lock is arranged to serve in securely holding the sashes in locked position. In this instance the stop pin 7 is located immediately above the upper edge of the outer portion of the beak head, so that a.

very slight movement of either sash will bring the pin 7 into collision with the beak head.

If desired, a wear plate 20 can be located at the lower end of each vertical stile 8 upon which the beak heads rub. This wear plate 20 if desired may further have an upstanding lip 19 arranged to engage the V branch 14 of the sash lock. This upstanding portion 19 performs a special function in that it draws the sash look toward the wear plate bringing the scarf edges a, of the stiles 9 and 10 into contact, as clearly shown in Fig. 2. I V

Whenever the lock is made to do serv:

ice as a window stop, as shown in Fig.

1, both sashes are forced against their battens to hold them in secured position, and preventing any rattling of the window frames. 7

f While it is impossible to open the widows as the beak head. will collide with the'stop" pins 5, the windows can at any time be closed, as in closing them the beak heads slide over the pins and finally drop below the same, so that the locks are self-closing or locking. 7

While I have shown and described the beak head as provided with the stop ledge 16, it should be'understood that this ledge is 7 tends the straight branch 14 of the V held Gopies of this patent may be obtained for an anti-rattling sash holderi be made to engage the stop oblique to the major portion of the look, as clearly shown. In the modification, the straight branch 14 ends: at a point immediately below the under surface of the body portion of the sash lock.

It is of course understood that any num-- ber' of stop pins 5. may be employed, and it' might further" be stated that I prefer using two locks in connection with each window, 7 as shown in Fig 5. i

The look as above described may be formed entire in one operation being stamped from sheet metal.

The lock is simple-and inexpenslve in construction and both durable and effieient in" operation, and the look further canjbe 'adjusted upon a window sash, with ease, ac-

curacy and despatch, andfbe'made to do lock and service as a window stop. and sash Having thus described my said invention what I claim as new anddesire to secure by UnitedStates Letters Patent'is:
